Operating System 
Windows 7 Professional 64-bit SP1 

AMD Athlon 64 X2 3600+ 25 °C 
Windsor 90nm Technology 

4,00GB Single-Channel DDR2 @ 334MHz (5-5-5-15) 

WinFast MCP61M2MA (Socket M2 ) 40 °C 

L1952TR (1280x1024@60Hz) 
NVIDIA GeForce 7300 GT 


My stationary computer keeps shutting down after some time without any error messages. It just shuts down instantly like it's been unplugged.When pressing the Power button it doesn't turn on, unless i unplug it from power outlet and then plug it back. Tried the following: 

- Scanned for viruses - no viruses(using Malware Anti-Malware) 

- Stress tested GPU , CPU and power supply using OCCT. Shut down didn't occure while stressed and the components didn't overheat; 

- Cleaned all the dust inside the Motherboard(including videocard,ram,processor, power supply); 
- Swapped the power supply, but the problem still persists; 
- Scanned memory with memtest - no errors; 
- Scanned SSD with chkdsk and no bad sectors or errors; 
- Reinstalled Windows 7 , the problem still persists; 
- Installed Linux Mint Serena, and still the same problem occurs; 
- Computer doesn't shut down while in Windows XP SP3; 
- When booting Windows 7 in Safe Mode it doesn't shut down too; 
- While in BIOS, it doesn't shut down; 
Any ideeas what can be the problem?

Wait until it shuts down again, then recover and immediately generate these 2 sets of reports:


Let's try looking at these 2 sets of reports:

Report Set #1)  Please run this report collecting tool (even though you may not be experiencing BSOD's) so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/
FYI - I don't often use the Perfmon report, so if it doesn't work please just let me know.

Please zip up the (.ZIP) files - do not use .RAR or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.

Report Set #2)  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on the "Administrative Events" heading
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504

While waiting for a reply, please monitor your temps with this free utility: 

SpeedFan v. 4.5.1 and later (free from here:  http://www.almico.com/sfdownload.php ) can log temperatures in a CSV file:
You may not need to log temps - if uncertain, please ask.

To make it work (log the temps to a file) you have to do BOTH of the below:

1. Enable logging in general: Configure...Log...check "Enabled" then click on OK to save.

2. Enable logging for specific checks: Configure...Temperatures..left click on each sensor, then click on "Logged" at the bottom of the Window (for our purposes we want them all) then once you've selected "Logged" for all sensors, then click on OK to save.

The log will be located at C:\Program Files (x86)\SpeedFan

Naming: log files are named SFLogYYYYMMDD.csv, where YYYY is the year (four digits), MM is the month (2 digits, zero padded) and DD is the day (2 digits, zero padded). If a file already exists by that name, the file that already exists is renamed according to the following naming scheme: SFLogYYYYMMDD-CCCC.csv, where CCCC is a increasing number. The new file is then created with the standard file name scheme.

Notes: whenever you change the options related with logging, SpeedFan starts a new log file.

NOTE:You may want to turn logging off when we're done - as I don't know it's impact on performance or on the system.

Looks like you know what your doing, one thing you didn't try is a good reseating of parts and clean em with electronic contact cleaner as you go, as well what the max heat you hit on your cpu with occt after 15min of full load all cores.


Ps, didn't know about that app.
